I am glad you posted this information as I am setting up my own retail website and I wasn't sure on how to implement SSL encryption. I used a website called SSL 247 to help create ssl certificate for my site as it is vital that both myself and any customers that use my site are adequately protected.
I am very much glad that it has become helpful to you. Best of luck I wish all success in your life. For your more help you are requested to Visit http://www.verisign.com/ssl/ssl-information-center/ecommerce-trust-ssl/index.html
